Mularkey went 2-14 in his first season with the Jaguars. In what could be viewed as an ominous sign for Mulareky, owner Shad Khan gave his assistants permission to search for other jobs last week.

Mularkey and Caldwell do have a relationship from their time in Atlanta. Mularkey was the team’s offensive coordinator for four years and during that time Caldwell was the team’s director of college scouting.

If Mularkey is fired, La Canfora speculates that San Francisco 49ers Greg Roman is likely to be the front-runner for the head coach opening.

Caldwell and Roman attended John Carroll University in Ohio, together in the 1990’s, and were roommates at the school, multiple reports have noted.
